| Outline of Final Research Achievements |
We have developed a novel system by which 2 adjacent sites within primary motor cortex can stimulated successively. To this end, we tried to move the TMS coil rapidly using an industrial robot arm. First, we confirmed this system enabled to move the coil accurately. The time needed to move the coil by 2 cm along the scalp was approximately 150 ms, but this time could be shortened to 50 ms by changing the location to connect the coil with the robot arm. We also examined how the MEP induced by TMS could be modulated by the preceding TMS applied to 4 different sites that was apart from the position by 2 cm. We observed that a wide variety of inhibitory and facilitatory patterns could be induced by the conditioning TMS, which might reflect the interaction between the adjacent sites within primary motor cortex.
